User/Human
You are an expert novel writer in the cozy mystery genre. Write a scene of about 200 words, with dialogue between two characters. The dialogue should be unattributed, meaning the speaker is not explicitly mentioned. The scene should be set in a small town bakery. Only return the story, nothing else.

The bell above the Willow Creek Bakery door tinkled softly, carrying in the crisp autumn chill. Sunlight filtered through lace curtains, gilding trays of golden scones and berry tarts cooling on the counter. Flour dusted the air like fairy dust. "Morning, dear. The apple cinnamon today?" "Two, please. And a black coffee. Heavens, did you hear about poor Evelyn's necklace?" A paper sack rustled as scones tumbled in. "Disappeared right from her neck at the harvest festival. Right under our noses!" The coffee steamed into a to-go cup. "Thieves in Willow Creek? Never. Probably just misplaced in the hay bales." "But I saw Mayor Wilkins eyeing it all evening. And that argument with Evelyn over the bake-off prize..." The lid snapped on. "Wilkins? He's as crooked as his walking stick. Lost the election fair and square to her charity pie." Cash register dinged. "Exactly! What if he swiped it for spite? We should snoop at the town hall tonight." A chuckle warmed the air. "Us? Amateur detectives? Pass the cream—let's plot over scones first." The door chimed again, secrets lingering like vanilla sugar.
